Gale Warning A gale warning is issued for coastal and marine areas when winds of 39 to 61 knots are expected, advising against sea travel for most vessels. Heavy Rainfall Warning A heavy rainfall warning is PAGASA's color-coded alert for expected rain accumulation, issued separately from wind signals since heavy rain can occur without strong winds. Hydrological Forecast A hydrological forecast projects river and reservoir water levels, used to anticipate flooding downstream of dams and major waterways during heavy rain events. Orange Rainfall Warning An orange rainfall warning signals 15 to 30 mm of rain per hour expected to continue for two or more hours, with flooding likely in many areas. PAGASA PAGASA, the Philippine Atmospheric, Geophysical and Astronomical Services Administration, is the national agency responsible for weather forecasting, typhoon tracking, and public weather warnings in the Philippines. Red Rainfall Warning A red rainfall warning signals over 30 mm of rain per hour expected to continue for two or more hours, PAGASA's highest rainfall alert, with severe flooding expected even in areas not normally prone to it. TCWS No. 1 TCWS No. 1 is raised when winds of 30 to 60 km/h are expected within 36 hours, PAGASA's lowest wind signal level.
